Muti' said, "I heard the Prophet, may Allah bless him and grant
him peace, say on the day of the Conquest of Makka, 'No Qurayshi will be
killed in custody from today until the Day of Rising.'" None of the rebels
of Quraysh except Muti' became Muslim. His name had been al-'As and the
Prophet, may Allah bless him and grant him peace, renamed him Muti' (obedient).
